  • Patent number: 6908192
    Abstract: A printing apparatus comprises a printing device and a laminating device that work in an integrated operation, such that in normal operation the print media extends between the printing device and the laminating device; the printing device comprises means for printing at least one plot on said media while it advances in a first media advance direction, and the laminating device comprises means for laminating at least one printed plot in a second advance direction of said print media which is opposite to said first advance direction. The laminating device may comprise means for selectively inactivating lamination when print media travels therethrough. A method for printing and laminating at least part of a print media in an integrated operation is such that printing of at least one plot is performed in a first advance direction of said print media and subsequent laminating of at least one printed plot is performed in a second advance direction of said print media, opposite to said first advance direction.

  • Patent number: 6854907
    Abstract: A method for substantially removing “roll-set curl” in a rolled print medium. Roll-set curl, as the name implies, may be defined as the “memory” a print medium has which causes the print medium to tend to return to the shape it had while on the core, once the print medium is unrolled. Additionally, a method for printing on both sides of a print medium in which a roll-set curl has been substantially removed. In one respect, according to a preferred embodiment, a take-up reel is utilized to substantially remove the roll-set curl.
